Monuments should not be trusted exhibition

Monuments Should Not Be Trusted brings together over 30 leading artists and groups from the “golden years” of the Socialist Federal Republic of Yugoslavia - the period between the early 1960s and the mid 1980s. Over 100 artworks and artefacts illuminate the key contradictions of this single party state – built after WWII on socialist principles, yet immersed in “utopian consumerism.” This is the first time in the UK that the art of this period, which has attracted increasing attention, has been shown in the context of the social, economic and political conditions that gave rise to it. It draws on new and innovative research on this period, and features many of its most celebrated artists. The exhibition begins with the rise of consumerism, midway through President Josip Broz Tito’s 37 year presidency, and ends a few years after his death in 1980. As well as artists’ works in moving image, collage, photography, sculpture and painting, the exhibition encompasses music, TV clips and fascinating artefacts, such as gifts made by workers for President Tito’s birthday, and relay batons which were carried across the country and ceremonially presented to him.

Retinoid-Related Receptor (ROR) alpha mRNA Expression Is Altered in the Brain of Male Mice Lacking All Ligand-Binding Thyroid Hormone Receptor (TR) Isoforms

In the vertebrate brain, the thalamus serves as a relay and integration station for diverse neuronal information en route from the periphery to the cortex. Deficiency of TH during development results in severe cerebral abnormalities similar to those seen in the mouse when the retinoic acid receptor (ROR)α gene is disrupted. To investigate the effect of the thyroid hormone recep-tors (TRs) on RORalpha gene expression, we used intact male mice, in which the genes encoding the α and beta TRs have been deleted. In situ hybridization for RORalpha mRNA revealed that this gene is expressed in specific areas of the brain including the thalamus, pons, cerebellum, cortex, and hippocampus. Our quantitative data showed differences in RORalpha mRNA expression in different subthalamic nuclei between wild-type and knock-out mice. For example, the centromedial nucleus of the thalamus, which plays a role in mediating nociceptive and visceral information from the brainstem to the basal ganglia and cortical regions, has less expression of RORalpha mRNA in the knockout mice (-37%) compared to the wild-type controls. Also, in the dorsal geniculate (+72%) and lateral posterior nuclei (+58%) we found more RORalpha mRNA in dKO as compared to dWT animals. Such differences in RORalpha mRNA expression may play a role in the behavioral alterations resulting from congenital hypothyroidism.

The role of life history traits in mammalian invasion success

Why some organisms become invasive when introduced into novel regions while others fail to even establish is a fundamental question in ecology. Barriers to success are expected to filter species at each stage along the invasion pathway. No study to date, however, has investigated how species traits associate with success from introduction to spread at a large spatial scale in any group. Using the largest data set of mammalian introductions at the global scale and recently developed phylogenetic comparative methods, we show that human-mediated introductions considerably bias which species have the opportunity to become invasive, as highly productive mammals with longer reproductive lifespans are far more likely to be introduced. Subsequently, greater reproductive output and higher introduction effort are associated with success at both the establishment and spread stages. High productivity thus supports population growth and invasion success, with barriers at each invasion stage filtering species with progressively greater fecundity.
